Frías is a town located in the northern part of the province of Burgos, in Castile and León, Spain.

Frias is aptly named in homage to the temperature of the water that flowed from the mountainous peaks draining into the Tobalina Valley.

There is first mention of Frias in the late 9th century but after the year 1000, it was incorporated into the kingdom of Navarre located in Burgos.

Frias would go on to be controlled by Diego Lopez de Haro, the Lord of Biscay in the late 11th century and Alfonso VIII in 1200.

After 1201, Frias was granted a set of laws and sense of freedom by Alfonso VIII that allowed them the right of succession, ability to elect a mayor, and tools to stimulate their economy.

With these laws enacted, Frias was able to thrive and prosper until it was granted the title of city by King John II in 1435.

Frias would continue to experience ebbs and flows of bondage and freedom until 1811 when feudalism was abolished in all of Spain.

The medieval old town has been declared Conjunto Histórico and retains its urban structure and special construction features.

It passes by La Canaleja, Rueda, Ronda, Rincón de Soto and Calzada streets.

Even in 1574 in some documents the converted “tax collector of Frías” from the mid 15th century, Juan Sanz de la Ussa, was recalled, wondering if he had been executed or forgiven.

Juan Sanz de la Ussa worked as a tax collector for the Velasco family and founded the Visitación chapel.

On the top of “La Muela” hill, its strategic position provides a privileged view of the valley and the bridge19.8M over Ebro River.
